A system control circuit checks a memory for data therein through a memory control circuit upon a pickup reaching the end of the disk. When at least a predetermined quantity of data remains in the memory, signaling sound generating means produces a signaling sound three times and a display portion is caused to flash. On the other hand, if the quantity of data remaining in the memory is not greater than a predetermined amount, the sound generating means produces a prolonged signaling sound once and causes the display portion to flash. The display operation is terminated if no disk change is made within a specified period of time thereafter.

L'invention est un circuit de commande qui examine le contenu d'une mémoire lorsqu'un capteur arrive à la fin d'un disque. Quand il reste une certaine quantité prédéterminée de données en mémoire, un dispositif d'alerte acoustique produit une tonalité d'alerte trois fois et un voyant se met à clignoter. Toutefois, si la quantité de données qui reste en mémoire ne dépasse pas une certaine quantité prédéterminée, le dispositif d'alerte acoustique produit une seule tonalité d'alerte prolongée et fait clignoter le voyant. Après une période déterminée, ce clignotement est supprimé si aucun changement de disque n'a été effectué entre-temps.
